Preparation of Polystyrene Sulfonic Acid
[0119]206 g of sodium styrene sulfonate was dissolved in 1,000 mL of ion-exchanged water. An oxidizing agent solution in which 1.14 g of ammonium persulfate was dissolved in 10 mL of water in advance was added dropwise at 80° C. with stirring for 20 minutes, and the solution was stirred for 2 hours. To the obtained sodium styrene sulfonate-containing solution, 1,000 mL of sulfuric acid diluted to 10% by mass and 10,000 mL of ion-exchanged water were added, and about 10,000 mL of polystyrene sulfonic acid-containing solution was removed by ultrafiltration. To the residue, 10,000 mL of ion-exchanged water was added, and about 10,000 mL of the solution was removed by ultrafiltration. This ultrafiltration operation was repeated 3 times.
[0120]To the obtained filtrate, about 10,000 mL of ion-exchanged water was added, and about 10,000 mL of the solution was removed by ultrafiltration. This ultrafiltration operation was repeated 3 times.

Preparation of Dispersion Liquid of poly(3,4-ethylenedioxythiophene) Doped with polystyrene sulfonic Acid
[0127]14.2 g of 3,4-ethylenedioxythiophene and a solution of 36.7 g of polystyrene sulfonic acid obtained in Production Example 1 in 2,000 mL of ion-exchanged water were mixed at 20° C.
[0128]The obtained mixed solution was held at 20° C. 29.64 g of ammonium persulfate dissolved in 200 mL of ion-exchanged water and an oxidation catalyst solution of 8.0 g of ferric sulfate were slowly added with stirring, and stirred for 3 hours, to cause a reaction.
[0129]To the obtained reaction solution, 2,000 mL of ion-exchanged water was added, and about 2,000 mL of the solution was removed by ultrafiltration. This operation was repeated 3 times.
[0130]To the treatment liquid after the ultrafiltration, 200 mL of sulfuric acid that was diluted to 10% by mass and 2,000 mL of ion-exchanged water were added, and about 2,000 mL of the treatment liquid was removed by ultrafiltration. To this liquid, 2...

Synthesis of polysulfoethyl methacrylate
[0132]216 g of sodium sulfoethyl methacrylate was dissolved in 1,000 mL of ion-exchanged water. An oxidizing agent solution in which 1.14 g of ammonium persulfate was dissolved in 10 mL of water in advance was added dropwise at 80° C. with stirring for 20 minutes, and the solution was stirred for 12 hours. To the obtained polysulfoethyl methacrylate-containing solution, 1,000 mL of sulfuric acid diluted to 10% by mass and 10,000 mL of ion-exchanged water were added, and about 10,000 mL of polystyrene sulfonic acid-containing solution was removed by ultrafiltration. To the residue, 10,000 mL of ion-exchanged water was added, and about 10,000 mL of the solution was removed by ultrafiltration. This ultrafiltration operation was repeated 3 times.
[0133]To the obtained filtrate, about 10,000 mL of ion-exchanged water was added, and about 10,000 mL of the solution was removed by ultrafiltration. This ultrafiltration operation was repeated 3 times. Wa...
